IMPROVEMENT IN sTovE-GRATES.

Specification forming part of Letters Patent No. 201,630, dated March 26, 1878; application led August 17, 1877.

' ing the application of my improvements; and

Figs. 2 and 3 are, respectively, a bottom-plan view and an end elevation `of the grate and its connections.

Similar letters of reference inthe drawings denote the same parts.

This invention has for its object to improve the construction of stove-grates, and especially grates for cooking-stoves, in respect to rendering them more efficient, durable, and less eX- pensive than those heretofore produced; and it consists in an improved construction and manner of supporting and operating the grate, which I will now proceed to describe, and point out in the claims.

In the accompanying drawings, A represents a section of a stove-casing; B, the fireboX; O, the ash-box, and Gr the grate. The grate G is provided at its ends with trunnions or journals J, which rest on sheave-pulleys P, journaled in brackets D, locatedat the ends of the grate-frame E.

'These brackets may be bolted to the grateframe, as shown in Figs. 2 and 3, or cast as a part thereof, if preferred.

The pulleys are each provided with journals,

' and can be easily slipped in and out of their bearings when desirable. The rear side of the grate rests upon a plain pulley, p, mounted on a short pin or screw-stud secured to the grate-frame, said pulley, besides afibrding an additional bearing for the grate in its movements, serving also to maintain its horizontal position and prevent it from turning accidentally.

Being supported entirely upon rolling surfaces, the grate is easily reciprocated or rattled.

It will be seen by reference to Fig. 1 that the grateframe extends beyond and behind the end Walls N N of the fire-box of the stove, and that consequently the pulleys located therein are completely sheltered from the re, and cannot become burned or warped by heat, nor clogged by cinders, but remain perfectly operative until worn out. In this respect I regard my invention as superior to any other known to me.

The grate may be reciprocated by power applied at either end or to the middle; and to dump it, it is tipped forward on its journals sufciently far to allow the contents of tire-box to pass to the ash-pit below.

I do not wish to confine myself to the peculiar form of grate proper represented in the drawings, as a double grate having suitable journals may be employed, made in separate sections, and connected and operated at one end by a lever-arm, or connected by two lever'- arms, and operated from the front, regarding such construction as covered by my invention, which consists in the arrangement of the supporting devices, rather than in the special form of grate itself.

.I claim as my invention- 1. A reciprocating stovegrate having journals supported on pulleys located outside the fire-pot, whereby.` the grate is enabled to be reciprocated and turned for dumping on the said pulley-bearings, substantially as described.

2. The sheave-pulleys P P, mounted in the grate-frame E, behind the end walls of the fire-box, in combination with grate G, having journals J, substantially as described.

3. The pulley p, supporting the rear side of the grate, in combination with the grate, grate-irame,and sheave-pulleys P P, substantially as described, for the purpose specified.
